Answer:
The yearly release of 
into the atmosphere is 
.
Explanation:
Annual production of CaO = 
Moles of CaO :
According to reaction, 1 mole of CaO is produced along with 1 mole of carbon-dioxide.
Then along with 
of CaO moles of carbon-dioxide moles produced will be:
of carbon-dioxide
Mass of 
moles of carbon-dioxide:
The yearly release of into the atmosphere is .
Answer:
0.21mol Ar (g)
Explanation:
To convert from litres to moles at STP we must divide the amount of litres by 22.4.
4.7 / 22.4 = 0.21mol Ar (g)
Answer:
B = the number of protons
Explanation:
The atom of every elements differ from each other because of number of protons they have.
Every atom consist of neutron, proton and electron. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron.
The number of neutrons may be same but every atom have different number of protons.
Neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.
Symbol of proton= P+
Symbol of neutron= n0
Mass of proton=1.672623×10-27 Kg
Mass of neutron=1.674929×10-27 Kg
